Cornerstone Defense Tech Stack

Defense cloud and mission engineering for U.S. government agencies

Information Services Herndon, Virginia 201–500 employees Founded 2014 Privately Held

Cornerstone Defense builds cloud infrastructure and mission-critical systems for defense and space customers. The stack reveals a mature, multi-cloud operation: Oracle (PeopleSoft, Exadata, OCI), AWS, Azure, and GCP, with heavy infrastructure-as-code tooling (Terraform, Ansible, CloudFormation). Active hiring is engineering-dominated (70 of 96 roles) and skewed senior, suggesting they're scaling delivery teams and migrating legacy workloads into modern cloud pipelines rather than building greenfield products.
